HELP with gas modelling!!

Arun

Hi all,

I am trying to model a system to detect leakage of gases while in transit. I intend to model gases being transported in drums, several of these drums being placed in containers. Incase the gases leak out of the drums, I'd like to determine the concentration of the gas present inside the container, at different regions in the container.

I am trying to use Pro-Star from the Star CD suite. Have modeled the container and drums in Star Design (as a '.ccd' file), but am unable to export it into Pro-Star. Please tell me how to go about it with this software (or any other better software). Also, please tell me what sort of an equation/relation will I be dealing with in this regard.

Would really appreciate any responses/suggestions. Thanks, Arun.
